Compco Industries - Weld Joint Information

Proper weld up of tank heads to shell sheets and other housings is crucial to product quality and safety. A perfect butt weld is necessary to insure proper mating of tank heads to their associated assemblies. Many of our customers choose to receive their tank heads joggled. Joggling is a process that helps facilitate fit-up and welding of tank heads to shell sheets. Joggling also helps form the gap necessary for the butt weld required by ASME and DOT pressure vessel codes. The joggling profile and weld requirements are outlined by figure UW-13.1 and Part UW-Welded Vessels in the ASME Boiler and Pressure Vessel Code, Section VIII Division 1, the latest revision of which is available only from The American Society of Mechanical Engineers. Compco Industries, through diligent quality control efforts, strives to produce a quality product that ensures safety, reliability, durability, and code compliance. All tooling and material is closely monitored and adjusted to ensure that Compco produces products that meet or exceed all relevant code requirements and design specifications.
